This is a real problem, because in my real application, I tried to use a very
similar order in a std::set<tmp*,CustomOrder>, defined like this:
struct CustomOrder {
bool operator()(const Tmp* a, const Tmp* b) const {
return a->get() < b->get();
}
};
STLport gives this assertion when inserting Tmp pointers with equal values
(returned by get() function):
/usr/include/stlport/stl/debug/_tree.h(63): STL error : Invalid strict weak
ordering predicate, if pred(a, b) then we should have !pred(b, a)
/usr/include/stlport/stl/debug/_tree.h(63): STL assertion failure:
!_M_non_dbg_cmp(__rhs, __lhs)
